PAPER-MAKING MACHINE.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Original application filed August 22, 1906, Serial No. 331,617. Dividedand this application filed July 1, 1908. Serial To all whom it mayconcern:

Be it known that I, J AMES WV. PAGKER, a citizen of the United States,residing at Glens Falls, county of Warren, and State of New York, haveinvented certain new and useful Improvements in Paper-Making Machines,of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.

Similar characters refer to similar parts in the several figurestherein.

The subject-matter of this application is a divisional part of theoriginal application filed by this applicant Aug. 22, 1906, forimprovements in reel-belt tighteners for paper-making machines, andgiven the Ser. No. 331,617.

When calender rolls are used in a paper machine for putting a smoothfinish on the paper, the calendered paper is fed from such rolls to aset of drums or reels, first to one reel until filled, and then toanother reel. The reels are so arranged that having wound the requiredamount of paper from the calenders upon one reel, it is possible to stopthat reel, and by breaking the sheet of paper and starting the otherreel to wind the paper on said other reel without stopping the calenderrolls, thus making the paper-making process continuous. After havingwound the required amount of paper on one reel, the reel is stopped andconnected with a winder or slitter which removesthe paper from the reel,leaving it in rolls or sheets as finished product, the reelbeing-emptied to receive the paper from the calender rolls when itscompanion reel has been filled. The calender rolls of the papermakingmachine travel at a uniform rate of speed which necessitates a variablespeed in the reels because the diameter of the paperroll upon the reelsincreases with each winding of the paper upon the reel. It is necessarytherefore to provide means for accommodating the speed of the reels tothat of the calender-rolls which has been done by independently drivingeach reel by means of a slip-belt, the tension of the belt being soadjusted by means of belt-tighteners that the belt will slip upon thereel-driving pulley sufficiently to accommodate the speed of the reel tothat of the calender-rolls, the friction of the slip-belt upon itspulley being sufficient to produce a tension on the paper between thereel and the calender-rolls. When the diameter of the paper-roll uponthe reel becomes greater than the diameter of the reel more power willbe required to produce the same tension upon the paper between thepaper-rolls and the calender-rolls and it is frequently necessary toreadjust the belt tightener. The belts and belt-tighteners arenecessarily located on the rear or further side of the reelingmechanism, while the attention of the operator is required at the frontof such mechanism to inspect the work from time to time and see that theoperation is being properly carried on. Every time a reel is filled itis necessary to stop the driving mechanism of that reel and to start thedriving mechanism of the empty reel; it is also necessary at times tochange the adjustment of the belt-tighteners. To accomplish this work ofstarting, stopping and readjusting it has heretofore been necessary forthe operator to travel from the front to the rear side of the machine,the means for starting, stopping and adjusting, being located on therear or further side of the machine in proximity to the belts andbelt-tighteners.

The object of this invention is to provide means whereby 'the operatorcan stop and start the reels, as well as adjust and read just thetension of the belt-tighteners upon the reel-driving belts from hisposition in front of the machine, thus saving the time formerly requiredto pass from the front to the rear end of the machine effecting not onlya saving in time of the operator, but a saving in the product of thepaper-making machine for the reason that, when one reel has been filledwith paper from the calenders and the sheet of paper delivered from thecalenders broken, the paper product, which is delivered at the reelingmechanism before the empty reel is started, will become waste productwhich is torn from the sheet before the winding upon the empty reelcommences.

The invention consists in providing mechanism for operating thebelt-tighteners of the two reels which extends to the front of themachine within reach of the operator, as will hereinafter be more fullydescribed and pointed out in the claims.

Referring to the drawings :Figure 1 is a view in side elevation of thereeling mechanism showing the improved means for operating thebelt-tightener. Fig. 2 is a view in elevation of the rear end of themachine which is the right hand end, as seen in Fig. 1. Fig. 3 is a viewin end elevation of the opposite or forward end of the machine. Fig. 4is a horizontal, longitudinal middle section taken on the broken line 44.in Fig. 1. Fig. 5 is a View in side elevation of a cable driving wheeldetached. Fig. 6 is a vertical, middle, transverse section of the wheelshown in Fig. 5, showing a portion of the cable attached thereto. Fig. 7is a view in perspective of the adjusting nut for securing thehand-lever in posit-ion, detached. Figs. 5, 6 and 7 are drawn upon anenlarged scale.

The frame 1, supports the belt-reels, 2 and 3, fixed upon shafts, 4 and5, rotary in bear ings secured to the framework. The driving-pulleys, 6and 7, are also fixed upon the reel shafts and actuated by slip-belts, 8and 9, shown partly broken away. These belts are adapted to be tightenedby means of the loose pulleys, 10 and 12, rotary in supporting bearings,13, mounted upon the outer ends of arms, 14, oscillatory upon the reelshafts, 4 and 5, in the usual manner of similar belt-tighteners. Thearms, 14, each form a part of a bell-crank lever, the other arms, 15, ofthe bell-crank lever being provided with segments, 16 and 17, adapted toreceive the ends of an actuating cable traveling on a loose wheel and adriving-wheel. The cable, 20, secured by bolt, 21, at the upper end ofthe segment passes down over the face of the segment around theactuating wheel, 22, and up over the wheel, 23, and down onto thesegment, 17, its lower end being secured to the lower'end of the segmentby means of the bolt 24. The other segment, 16, is connected in asimilar manner by cable, 26, with the actuating wheel 27. As a means foroperating these two actuating wheels, 22 and 27, a pair of shafts areextended from the wheels out to the front end of the machine where theyare provided with operating hand-levers. The tubular shaft, 30, uponwhich the wheel, 27, is fixed is rotary upon the shaft, 31, upon whichis fixed wheel 22. The latter shaft passes through the tubular shaft andis rotatory in stationary bearings 32 and 33. The inner shaft, 31, isprovided at its forward end with a hand-lever, 34, fixed thereon, andthe tubular-shaft is provided at its forward end with a similarhand-lever, 35, fixed thereon. As a means for securing the shafts andhand-levers in differing positions, segments, 40, provided with annulargrooves, 41, one for each handle, are erected from the stationarybearings 33. each provided with an adjusting-screw, 42, and ascrew-threaded nut, 43, having a middle screw-threaded aperture, 44,adapted to receive the adjusting screw and the grooved flange, 45,adapted to enter and travel in the annular grooves 41. The hand-leversare provided with handles 46, and hubs 47 and 48. As a means forpreventing the cables from slipping on the actuatingwheels, 22 and 27, anotch 50 (see Figs. 5 and 6) is cut in the periphery of the wheeladapted to receive a cross-bar, 52, through which the cable passes, thecable being prevented from slipping in the cross-bar by means of a pin53. It is obvious, however, that any form of rope, cable or chain, maybe employed, as for example, a sprocket-chain and sprocket-wheels topreventthe cable from slipping on the actuating-wheels.

The operation of the improved reel belt tightening mechanism is asfollows: When one of the reels, as for example, reel, 2, has receivedthe desired amount of paper from the calender-rolls of the paper-makingmachine, the belt, 8, which drives it is loosened by a movement of thehand-lever, 35, from the position shown in Fig. 3 to the left in linewith hand-lever, 34, which rocks the tubular shaft, 30, and through theactuating-wheel, 27, cable, 26, and bell-crank lever having the arms, 14and 15, to move the loose pulley, 10, from the position shown in Fig. 4to the relative position of loose pulley, 12, shown in the same figurewhich so loosens the driving-belt, 8, as to allow the wheel to stop.However, before stopping the filled reel, the empty reel, 3, is startedby swinging the hand-lever, 34, from the position shown in Fig. 3 to theright, thereby rocking the inner shaft, 31, and through the actuatingwheel, 22, cable, 20, and connecting bellcrank lever, forcing the loosepulley, 12, against the belt, 9, to tighten the same sufficiently todrive the reel 3. hen the filled reel is stopped as before described,the sheet of paper being fed to it is broken and immediately transferredto the empty reel which has been put in motion, as before described, andthe paper sheet fed to that belt-reel until such reel is filled, thepreviously filled reel having been emptied in the meantime, or an emptyreel substituted for it, whereupon the sheet of paper is again brokenand trans ferred to the empty reel, the filled reel being stopped simplyby reversing the actuating hand-lever as previously described. In thisway, the sheet of paper coming from the calender-rolls is transferredfrom one empty reel to another without stopping the papermaking machine,thereby rendering the paper-making process continuous. By hav- Thehand-levers areingthe hand-levers, by means of which the reels arerespectively, started, stopped and speed-regulated, located at'the frontend, or side, of the machine, within easy reach of the operator while heis in position to watch the operation of the machine and break andtransfer the sheet of paper from one reel to another much time is savedin effecting such changes and the same can be accomplished with littleor no waste of paper.

What I claim as new and desire to secure by Letters Patent is 1. In apaper-making machine, the combination with a plurality of reels;reel-shafts; driving-pulleys one on each reel-shaft; a drive-belt foreach pulley; levers loosely mounted one upon each reel-shaft, and loosepulleys, one upon each lever, engageable with its appropriatepulley-driving belt; of a pluralit of neighboring rock-shafts parallelto, an coextensive with, the reel-shafts; actuating connections betweenthe pulleysupporting levers and the rear ends of the rock-shaftsrespectively; and means on the front ends of the rock-shafts foroperating such shafts successively and independently, one of another,whereby a sheet of paper continuously fed with constant speed upon suchreels can be easily and quickly transferred from one reel to the otherwith a minimum waste of paper, and a practically constant winding orunwinding tension maintained upon both reels at the same time.

2. In a paper-making machine, the combination with a reel-supportingframe having front and rear ends; a plurality of reelshafts extendingfrom front to rear; reels rock-shafts, respectively; and means on thefront ends of the rock-shafts for operating such shafts independentlyone of another.

3. In a paper-making machine, the combination with a reel-supportingframe having front and rear ends; a plurality of reelshafts extendingfrom front to rear; reels fixed, one upon the front end of eachreelshaft; reel-driving belt-pulleys fixed, one upon the rear end ofeach reel-shaft; levers, loosely mounted, one upon the rear end of eachreel-shaft; and loose belt-engaging pulleys, one upon each lever; of aplurality of rock-shafts concentric to one another, one shaft, or more,being tubular and rotatory about another; suitable bearings for therock-shafts; actuating connections between such shafts and pulleysupporting levers respectively; and means for operating the rock-shaftssuccessively.

In testimony whereof, I have hereunto set my hand this 30th day of June,1908.
